Not to be cute, but there’s a short and a long reply to the question”What causes ménopause?” Allow me to give the brief answer , and then backtrack into the long response. In short, the reason for menopause is falling levels of hormones released from the ovaries. Now for the longer answer.
These hormones, estrogen and progesterone form one-half of a feedback loop between the ovaries and the brain. The esprit stimulates ovarian secretion of estrogen via the release of follicle stimulating hormone (FSH) from the pituitary gland. It stimulates the release of progesterone from the ovaries with luteinizing hormone (LH), also in the adrenal gland. These four hormones, originating from the ovaries and the brain through the pituitary gland, form a communication system that modulates the daily cycle of reproduction.
The rhythmic rise and fall of the hormone levels underlies the rhythm of the reproductive cycle. Estrogen release at the start of each menstrual cycle, under the advice of FSH, stimulates the build from the lining of the utérus, in preparation for implantation of a fertilized egg. In the middle of the menstrual cycle that a surge of luteinizing hormone in the pituitary stimulates release of an egg.
LH also stimulates the secretion of progesterone that keeps the uterine lining. Eventually the ovaries stop responding to the stimulation of the mind. The rhythmic dance involving the brain and ovaries then comes to a stop, and the monthly cycle also stops. This shift is gradual rather than abrupt. The ovarian production of progesterone and estrogen declines gradually over a period of years. During this transition period the mind does its best to maintain testostérone and estrogen levels up by releasing more FSH and LH, respectively. The combination of estrogen and progesterone and greater than normal FSH and LH are responsible for the symptoms of premenopause and périménopause such as bouffées de chaleur, sueurs nocturnes, sécheresse vaginale, irritability, fatigue and much more.
Gardez à l'esprit
Every girl who’s born has a fixed number of eggs in their ovaries. The amount falls over the next decade and a half, to about three hundred million. Then each month numerous eggs older and one is published. At exactly the exact same time, many eggs deteriorate. So gradually the amount of eggs continues to diminish. Estrogen is secreted from the follicle which holds the egg while it evolves. After the egg is released, the follicle is changed and starts to secrete progesterone.
Eventually the amount of follicles that grow each month starts to drop. And so does the quantity of estrogen and progesterone being released from the uterus. When the amounts of estrogen and progesterone drop, the monthly cycle starts to falter and then stops completely. What causes menopause symptoms? The sex hormones progesterone and estrogen impact many body organs aside from the reproductive system (breasts, uterus, vagina). When the levels of these hormones starts to clot in perimenopause, one of the primary symptoms is irregular menstrual cycle, or even lighter or heavier menstrual flows.
Bouffées de chaleur
Another very frequent complaint is hot flashes and flashes, which can be experienced by 80-85percent of American girls as they transition through menopause. Hot flashes and night sweats are caused by a disturbance of the brain center that monitors and regulates body temperature. Normally the mind monitors body temperature and keeps it within a particular range for our security.
Dropping progesterone and estrogen levels disrupt this system. The mind erroneously interprets normally safe variations in body temperature as harmful, and makes heroic attempts to bring back our temperature to normal. Hot flashes and flashes are a strategy to cool down the body, bringing down body temperature.
Remember when you were a kid and you had a fever? At some stage the fever broke. It was when your mind decided you’re too hot and stimulated the release of sweat to cool you down. This is akin to the sweats experienced following a bouffées de chaleur. Menopause complaints are largely caused by dropping estrogen levels. A excellent natural remedy is located in phytoestrogènes. These are weakly estrogenic plant compounds found in herbs and nourriture. Phytoestrogens provide a safe method to bridge the difference of falling estrogen levels, to thereby relieve menopause related ailments.
